If 5.0 A of battery current passes through the outside leads of a 4-wire current span spaced at 30 m (100 ft), resulting in a voltage drop of 5.0 mV with the test current applied and of 1 mV without the test current, what is a the calibration factor of the current span? A. 0.00025 A/mV B. 4.0 A/mV C. 1.25 A/mV D. 5.0 A/mV - ANSWER-C. 1.25 A/mV I = 5 A EC = 5 mV ENC = 1 mV K = I/(EC - ENC) = 5 A/(5 mV - 1 mV) = 1.25 A/mV Polarized potentials are measured A. when the rectifiers are...
